摘要
矿山井下工作环境十分恶劣,经常造成电气设备绝缘损坏,给井下工作人员带来巨大的安全隐患。为有效检测电网的整体绝缘状况,在井下低压配电IT系统设计中,需采用绝缘监测系统。该系统的应用可有效识别电网中绝缘的退化情况,及时定位故障线路,实现对电网的良好可视性,最大限度降低人员遭受电击的危险。
The hostile working environment under the mine shaft often gives rise to the damage of electrical equipment insulation, and therefore brings about huge hidden safety hazard for people working underground. In order to effectively detect the whole insulation condition of power system, insulation monitoring system should be adopted for low--voltage distribution IT system under the shaft in the design. The application of the monitoring system can effectively identify degeneration of insulations in power system and timely locate faulty lines, obtain a good visuality of power system and maximum reduce the risk of getting electrocuted.
